The MAX961ESA+ is an ultra-high-speed Beyond-the-Rail Comparator with internal hysteresis. This device is optimized for single +3 or +5V operation. The input common-mode range extends 100mV Beyond-the-Rails™ and the outputs can sink or source 4mA to within 0.52V of GND and VCC. Propagation delay is 4.5ns (5mV overdrive), while supply current is 5mA per comparator. The MAX961 have a shutdown mode in which they consume only 270µA supply current per comparator. The MAX961 provide complementary outputs and a latch-enable feature. Latch enable allows the user to hold a valid comparator output.
